The T website says they'll be shuttle buses between Alewife and Harvard the Saturday and Sunday of AB.
(Grumble, grumble.) Hopefully the other lines won't have shuttles, but checking the T website is a good idea.

while it definitely is better suited for City of Boston section (actually i'm fairly certain there is one there too), i'm going to use this opportunity to show people who may have missed it on our social media platforms about this opportunity.
